Stage 1 Pre-filtration Two stage

10-1 micron pre-filter is designed to get rid of sediments, sand, & scale down to 1 micron.

Stage 2 Activated Carbon absorption

Coconut shell activated carbon filters, reduces elements that cause water to taste and smell unpleasant, including the taste and odour of chlorine, pesticides & herbicides.

Stage 3 Reverse Osmosis Membrane

Uses ordinary tap water through an extremely fine semi permeable membrane which filters the water down to molecular level, reducing arsenic, lead, fluoride, aluminum, nitrates, giardia and cryptosporidium leaving available the highest quality, pure & clean water on tap.

Stage 4

Premium coconut carbon provides great tasting drinking water.

Alkaline Filter (optional)

Water Alkaliser effectively raises PH levels as well producing antioxidants energized qualities. When water passes through the Alkaliser is breaks up the clusters of water molecules into smaller clusters, this makes easier for your body to absorb so you stay better hydrated.


  1. Super ceramic           – increases water taste by emitting FIR
  2. Silver antibacterial  – antibacterial deodorizing effect and heavy metals removal function
  3. Alkaline ball             – make alkaline water
  4. Negative iron ball   – emit negative ion
  5. Hexagonal ball        – make energy water
  6. Tourmaline ball      – make smaller water cluster
  7. Antioxidant Ball     – ORP↓, NMR↓ PH↑
